The in these Lott-norm nnd mnkinot the line.

is'afuil, clear,and exact description-thereof, suflicient to enable those skilled in the'art to which my invention' appertains to make and: use the same, reference being had to the accompanying drawing making part of this specification and to thedettersjand figures marked thereon. f

The nature of myinvcntion consists in so constructing the rotating device and the bow or pendent ring, and so arranging them With'reintion to each other that, by turning down the how, the rotating device is thrown into gear with the mechanism which operatesthe hands.

In stem-setting watches, as ,previously constructed,

it has been usual, in addition to the stem-turning gear,

whereby the hands are adinsted, or set forward or hackward, as required, to cinploy a pin or -spring', arranged to protrude vfrom the'case; and requiring a separate application of pressure or force-say, by the thumb or finger-infers andwhile turning the rotating device at the stem, for the purpose of locking said rotatingdevice with the cannot: or minnte-hand-operating pinion of the watch. This,-h0wevel',is very objectionahis, not only on account of the double manipulation requisite to set the'hands', but also on account of the liability to accidental and improper adjustment of them 1 by some casual outside contact with and action on the stem-gearing pin or spring, and turning of the attachr ment that is used for setting the hands.

The'dificulties referred to are obviated in my inventlon by making automatic, consequent on the adjustment of the pendent bow of the stem when the cap or a portion 'ofthe case only is-open, the gearing of the rotating device at the stem with the cannonpinion of the watch, the pendent bow controlling the action of the rotating device. 1

In the aocompanyingdrawing- Figurel represents, on an enlarged scale, a side or fiice view in section of a watch-case, with stem and pendent bow attached, and such portion of. the intorlor mechanism as relates to my invention.

Figure 2 is a transverse section of the same.- I

1 Figure 3 is a similar view, representing in full and dotted lines diii'erent positions of certain parts or (16-- vicel as controlling the setting of the hands by or at the'stem.

A represents the rim "of the case; B, the pendent or stem; and

O, the bow or pendent ring.

The bow 0 is divided whole it is hung'in the stem so as to'admit of a spindlig'D, passing up through the latter. 4 I The spindle D is provided with a milled, cap or rosehead, a, on its exterior end, to facilitate the turning of it by the fingers in setting the hands of the watch;

and, passing through the rim into the body of the case,

and'supported by suitable bearings, it carries, near its opposite or inner end, a clutch, b, the inner face 'of which, is made to form, or has attached to it, a con- ,trate wheel, 0.

The clutch b is made to turn with the spindle D, and also to slide longitndinallylon it, for the purpose et throwing said spindle by theicontrate wheel 0 in or out of gear with a pinion, d, that meshes through a train of spur-wheels or pinions, e f, with the cannonpinion y of the'watch.

On one end .11 of the bow Q, where it enters the stem, is an eccentric pin or projection, m, which is so pitched in relation to a sliding rod or pin, 71, passing from the stem into the bodyof the case, that when the bow is extended, as in figs 1 and 2, it is out of gear'or cont: ct with said sliding rod and remainsso even when the bow is turned down on the. closed cap E or other 'stopor guard to it; but on openingor removing the guardsay, "opening the cap E to see the position of the hands and amountof adjustment necessary to give them-then, on turning'the bcwO yetfnrther down, as represented in dotted lines in fig. 3,:(which the inn oval of the stop orgnard-orppcning of-thc cap now admits oi;) the eccentric pin 1 is, brought to bear and press inward the sliding pin lh, which teaches and compresses a spring,.1', ex'tendin'g; partly around the limon the inside of the case v This spring'i has a tendency to keep pressed,;-outwmd the sliding pin h, which, when forwd inwardtby the action of the eccentric pin in connected with the how 0, as described, in oompressingsaid spring causes the latter to bear-and drive inwards. branch or arm, j, of a spring clutch-lever, It, said branch or arin working'through a suitable guiding cavity or aperture in a 'flxed bracket or plate, I, and the free'endof the clutchlever It being forked to lit the clutch b.

The lever is being forced inward or compressed, it being of a spring or elastic character at its attachment u to the case, causes the clutch b -to slide inward, and with it the co'ntrate wheel 0, which is accordingly thrown into gear with the pinion d, so that by turning the milled cap a of the spindle D to the right or to the left the hands of the watch are set forward or backward, as required; but on again throwing hack oriextending or commencing to lift the how 0, the ooh centric pin in is released frompressnre on the sliding rod in, which the spring 6 throws ou ward, while thg spring clutch-lever k, in being'relieved from the notion of the spring 1', also shoots backand draws with it an e'lutoh which detaches the eontrate wheel 0 from gear with the pinion (I, so that turning the milled cap a and spindle D will have no efl'eot upon the setting mechanism of the watch; and' the closing of thecap E or putting into action the stop or guard secures or looks the same out of' gear, without regard to the position of the bow, which may then heeither closedor entended. 7

As the pendent how can operate upon the setting mechanism only when the case is open or the stop or guard in action, it will. be seen that the partseanuot he accidentally thrown into gear when the case is open.

The winding of the watch at the stem or otherwise may be effected by any suitable means, which it is not necessary here to describe."

What I claim as my invention, and desire to secure by Letters Patent; is-

1. A stem-setting watoh,'so constructed that the setting mechanism .is thrown into gear by turning down the pendent ring or how when the frontcap or casejs' open, substautiallyas shown and described.

2. Theeombinatio'n of the cap or guard E with the pendent how Oand hand-setting mechanism, whereby the said cap while closed is made to prevent the bow from throwing the hand-setting mechanism in gear, substantially as shown and described.
